What the Data Shows

Threat actors are no longer recycling old credential dumps. In Q1 2026, 72% of verified breaches came from direct compromises of live systems: government registries, telecom databases, financial platforms, and enterprise applications. More than 95% of those breaches exposed PII beyond credentials, including phone numbers, physical addresses, national IDs, and financial identifiers.

Why Constella?

Every statistic in this report is drawn from verified, deduplicated breach data, not raw scraped volume. Constella hunts breaches across the surface, deep, and dark web, then applies machine learning deduplication, agentic AI validation, and expert attribution before a single record enters the Data Lake. The result is identity risk intelligence you can act on.
